  • How to avoid MissingMethodException?

    - by Dimitri C.
    If .NET 3.5 is installed, but not .NET 3.5 SP1, WaitHandle.WaitOne(int) throws a MissingMethodException. I'd like to be notified earlier on if the correct version of the .NET libraries is not available, for example when the application is started. Is this possible? Update: So my question question is twofold: a) How can I determine which version of the .NET library is required by an application? b) How can I determine the currently installed version of the .NET library?

  • How do I use Fluent NHibernate with .NET 4.0?

    - by Tomas Lycken
    I want to learn to use Fluent NHibernate, and I'm working in VS2010 Beta2, compiling against .NET 4, but I'm experiencing some problems. Summary My main problem (at the moment) is that the namespace FluentNHibernate isn't available even though I've imported all the .dll assemblies mentioned in this guide. This is what I've done: 1. I downloaded the Fluent NHibernate source from here, extracted the .zip and opened the solution in VS. A dialog asked me if I wanted to convert the solution to a VS2010 solution, so I did. 2. I then went into each project's properties and configured all of them to compile for .NET 4, and built the entire solution. 3. I copied all the .dll files from /bin/Debug/ in the FluentNHibernate to a new folder on my local hard drive. 4. In my example project, I referenced FluentNHibernate.dll and NHibernate.dll from the new folder. This is my problem: If I right-click on FluentNHibernate in the References list and select "View in Object Browser...", it shows up correctly. Now, when I try to create a mapping class, I can't import FluentNHibernate. This code: using FluentNHibernate.Mapping; namespace FluentNHExample.Mappings { } generates an error on the using statement, saying The type or namespace 'FluentNHibernate' could not be found (are you missing a using directive or an assembly reference?). The FluentNHibernate assembly is still in the list of References of my project, but if I try to browse the assembly in Object Browser again, it can't be found. What is causing this?

  • Best practise to send mass email within application (ASP.NET MVC 2, C#)?

    - by gurdan
    Whats the best way to implement mass email sending feature within web app? Two major cases: Email messages for separate registered users depending on their activities (just sending short reminders to user for ex about new posts in his created topic) "Send email for all registered users" functionality, it will be nice to have feature for system administrator to send some messages for all registered users. Of course adding all emails to recipient isn't the way we can go, because email addresses for each user are anonimous. As i understand for case nr1 there is no problem just create some email message via System.Net.Mail by creating new mail message and sending it... but what about case nr 2??? i guess smth like this: foreach(var emailAddress in emailAddresses) { MailMessage mail = new MailMessage(); mail.From = new MailAddress("jondoe@bla.net"); mail.To.Add(emailAddress); mail.Subject = "test"; mail.Body = "test"; SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587); smtp.Send(mail); } isn't the good way :) so the question is what is the best way to achieve this ? btw we have no possiblity to deploy some serive for email sending, this should be integrated into web application.

  • How to convert datatable to json string using json.net?

    - by Pandiya Chendur
    How to convert datatable to json using json.net? Any suggestion... I ve downloaded the necessary binaries... Which class should i use to get the conversion of my datatable to json? Thus far used this method to get json string by passing my datatable... public string GetJSONString(DataTable table) { StringBuilder headStrBuilder = new StringBuilder(table.Columns.Count * 5); //pre-allocate some space, default is 16 bytes for (int i = 0; i < table.Columns.Count; i++) { headStrBuilder.AppendFormat("\"{0}\" : \"{0}{1}¾\",", table.Columns[i].Caption, i); } headStrBuilder.Remove(headStrBuilder.Length - 1, 1); // trim away last , StringBuilder sb = new StringBuilder(table.Rows.Count * 5); //pre-allocate some space sb.Append("{\""); sb.Append(table.TableName); sb.Append("\" : ["); for (int i = 0; i < table.Rows.Count; i++) { string tempStr = headStrBuilder.ToString(); sb.Append("{"); for (int j = 0; j < table.Columns.Count; j++) { table.Rows[i][j] = table.Rows[i][j].ToString().Replace("'", ""); tempStr = tempStr.Replace(table.Columns[j] + j.ToString() + "¾", table.Rows[i][j].ToString()); } sb.Append(tempStr + "},"); } sb.Remove(sb.Length - 1, 1); // trim last , sb.Append("]}"); return sb.ToString(); } Now i thought of using json.net but dont know where to get started....

  • using System.Net.Mail To send smtp mail via google gets me a time out exception.

    - by Anicho
    Hey guys, I guess I got another asp.net question I am trying to send email using smtp authentication through google but I am constantly getting a timed out error and no idea what it might be from the following code its not my firewall or my isp blocking smtp ports so its most probably the code: MailMessage msg = new MailMessage(); String BodyMsg; BodyMsg = "Hey " + TxtBoxUsername.Text + "@" + "Welcome to Tiamo your username and password are:@Username: " + TxtBoxUsername.Text + "@Password: " + PasswordString + "@You have succesffully registered, you can now login." + "@Thank You@Tiamo Team"; BodyMsg = BodyMsg.Replace("@", System.Environment.NewLine); msg.To.Add(new MailAddress(TxtBoxEmail.Text)); msg.From = new MailAddress("[email protected]"); msg.Subject = "Re: Welcome to Tiamo"; msg.Body = BodyMsg; SmtpClient client = new SmtpClient() ; client.EnableSsl = true; client.Send(msg); and this is my web.config email smtp settings: <system.net> <mailSettings> <smtp from="[email protected]"> <network host="smtp.gmail.com" port="465" userName="[email protected]" password="MyLovelyPassword" defaultCredentials="true"/> </smtp> </mailSettings> Im completely exhausted so I thought the best thing is to pop up a question, hope you can help it will all be much appreciated... thanks anicho.

  • Why doesn't every class in the .Net framework have a corresponding interface?

    - by Thorsten Lorenz
    Since I started to develop in a test/behavior driven style, I appreciated the ability to mock out every dependency. Since mocking frameworks like Moq work best when told to mock an interface, I now implement an interface for almost every class I create b/c most likely I will have to mock it out in a test eventually. Well, and programming to an interface is good practice, anyways. At times, my classes take dependencies on .Net classes (e.g. FileSystemWatcher, DispatcherTimer). It would be great in that case to have an interface, so I could depend on an IDispatcherTimer instead, to be able to pass it a mock and simulate its behavior to see if my system under test reacts correctly. Unfortunately both of above mentioned classes do not implement such interfaces, so I have to resort to creating adapters, that do nothing else but inherit from the original class and conform to an interface, that I then can use. Here is such an adapter for the DispatcherTimer and the corresponding interface: using System; using System.Windows.Threading; public interface IDispatcherTimer { #region Events event EventHandler Tick; #endregion #region Properties Dispatcher Dispatcher { get; } TimeSpan Interval { get; set; } bool IsEnabled { get; set; } object Tag { get; set; } #endregion #region Public Methods void Start(); void Stop(); #endregion } /// <summary> /// Adapts the DispatcherTimer class to implement the <see cref="IDispatcherTimer"/> interface. /// </summary> public class DispatcherTimerAdapter : DispatcherTimer, IDispatcherTimer { } Although this is not the end of the world, I wonder, why the .Net developers didn't take the minute to make their classes implement these interfaces from the get go. It puzzles me especially since now there is a big push for good practices from inside Microsoft. Does anyone have any (maybe inside) information why this contradiction exists?

  • Guaranteed way to find the ildasm.exe and ilasm.exe files regardless of .NET version/environment?

    - by m-y
    Is there a way to programmatically get the FileInfo/Path of the ildasm.exe/ilasm.exe executables? I'm attempting to decompile and recompile a dll/exe file appropriately after making some alterations to it (I'm guessing PostSharp does something similar to alter the IL after the compilation). I found a blog post that pointed to: var pfDir = Environment.GetFolderPath(Environment.SpecialFolders.ProgramFiles)); var sdkDir = Path.Combine(pfDir, @"Microsoft SDKs\Windows\v6.0A\bin"); ... However, when I ran this code the directory did not exist (mainly because my SDK version is 7.1), so on my local machine the correct path is @"Microsoft SDKs\Windows\v7.1\bin". How do I ensure I can actually find the ildasm.exe? Similarly, I found another blog post on how to get access to ilasm.exe as: string windows = Environment.GetFolderPath(Environment.SpecialFolder.System); string fwork = Path.Combine(windows, @"..\Microsoft.NET\Framework\v2.0.50727"); ... While this works, I noticed that I have Framework and Framework64, and within Framework itself I have all of the versions up to v4.0.30319 (same with Framework64). So, how do I know which one to use? Should it be based on the .NET Framework version I'm targetting? Summary: How do I appropriately guarantee to find the correct path to ildasm.exe? How do I appropriately select the correct ilasm.exe to compile?

  • Looking for Hardware that will easily interface with my .NET code.

    - by SkippyFire
    I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

  • Free solution for automatic updates with a .NET/C# app?

    - by a2h
    Yes, from searching I can see this has been asked time and time again. Here's a backstory. I'm an individual hobbyist developer with zero budget. A program I've been developing has been in need of constant bugfixes, and me and users are getting tired of having to manually update. Me, because my current solution of Manually FTP to my website Update a file "newest.txt" with the newest version Update index.html with a link to the newest version Hope for people to see the "there's an update" message Have them manually download the update sucks, and whenever I screw up an update, I get pitchforks. Users, because, well, "Are you ever going to implement auto-update?" "Will there ever be an auto-update feature?" Over the past I have looked into: WinSparkle - No in-app updates, and the DLL is 500 KB. My current solution is a few KBs in the executable and has no in-app updates. http://windowsclient.net/articles/appupdater.aspx - I can't comprehend the documentation http://www.codeproject.com/KB/vb/Auto_Update_Revisited.aspx - Doesn't appear to support anything other than working with files that aren't in use wyUpdate - wyBuild isn't free, and the file specification is simply too complex. Maybe if I was under a company paying me I could spend the time, but then I may as well pay for wyBuild. http://www.kineticjump.com/update/default.aspx - Ditto the last sentence. ClickOnce - Workarounds for implementing launching on startup are massive, horrendous and not worth it for such a simple feature. Publishing is a pain; manual FTP and replace of all files is required for servers without FrontPage Extensions. I'm pretty much ready to throw in the towel right now and strangle myself. And then I think about Sparkle... EDIT: I came across SparkleDotNET just then. Looks good, though the DLL is 200 KB. Don't know if that's really that big of an issue, though.

  • Can SOTI's MobiControl software interfere with an ASP.Net web service?

    - by MusiGenesis
    We have a set of WinMo (5.0) devices running a .NET CF application that talks to an ASP.Net web service running on a server. The devices connect to the network either via ActiveSync through a networked PC or directly to the network via an Ethernet dongle. In our development environment, the communication between devices and web service is 100% reliable. In our production environment, the communications are failing erratically and unpredictably. Sometimes calls to the web service (even to a simple test call that just returns a boolean) begin failing every time on a particular device, with the error message "Could not establish connection to network." This is usually fixed by flip-flopping the selected combo box values on the SETTINGS | NETWORKS screen. Sometimes calls on a particular device begin failing with a generic "WebException" message. The fix for this problem (so far) is either to reset the device (i.e. reinstall the OS) or else it just can't be fixed on some devices. To the best of our knowledge, everything about the DEV and PROD systems are the same (same server and device specs). The most obvious difference to us is that the PROD devices are all controlled by SOTI's MobiControl (which is server-side software that communicates with a SOTI client application installed on each device), whereas our DEV environment does not have SOTI installed anywhere (obviously we should have it there as well - long story). Does anybody have any experience with SOTI MobiControl and/or know of any documented problems where SOTI interferes with other communication mechanisms on a device?

  • Are there size limitations to the .NET Assembly format?

    - by McKAMEY
    We ran into an interesting issue that I've not experienced before. We have a large scale production ASP.NET 3.5 SP1 Web App Project in Visual Studio 2008 SP1 which gets compiled and deployed using a Website Deployment Project. Everything has worked fine for the last year, until after a check-in yesterday the app started critically failing with BadImageFormatException. The check-in in question doesn't change anything particularly special and the errors are coming from areas of the app not even changed. Using Reflector we inspected the offending methods to find that there were garbage strings in the code (which .NET Reflector humorously interpreted as Chinese characters). We have consistently reproduced this on several machines so it does not appear to be hardware related. Further inspection showed that those garbage strings did not exist in the Assemblies used as inputs to aspnet_merge.exe during deployment. aspnet_merge.exe / Web Deployment Project Output Assemblies Properties: Merge all outputs to a single assembly Merge each individual folder output to its own assembly Merge all pages and control outputs to a single assembly Create a separate assembly for each page and control output In the web deployment project properties if we set the merge options to the first option ("Merge all outputs to a single assembly") we experience the issue, yet all of the other options work perfectly! My question: does anyone know why this is happening? Is there a size-limit to aspnet_merge.exe's capabilities (the resulting merged DLL is around 19.3 MB)? Are there any other known issues with merging the output of WAPs? I would love it if any Assembly format / aspnet_merge.exe gurus know about any such limitations like this. Seems to me like a 25MB Assembly, while big, isn't outrageous.

  • Why does trying to unit test with two .NET 4.0 assemblies under NUnit 2.5.4 fail?

    - by GiddyUpHorsey
    I have an MSBuild script that uses NUnit to run tests in two assemblies. These were on .NET Framework 3.5 and it worked perfectly for a long time. The command line was: (actual paths & names simplified) nunit-console tests1\bin\debug\tests1.dll tests2\bin\tests2.dll I've upgraded to VS2010 and have now made the two test assemblies target .NET 4.0. I've also upgraded to NUnit 2.5.4. I can unit test a single assembly with the following: nunit-console tests1\bin\debug\tests1.dll /framework=4.0.30319 It works fine with either tests1.dll or tests2.dll. If I try to specify both like before, it now fails. nunit-console tests1\bin\debug\tests1.dll tests2\bin\debug\tests2.dll /framework=4.0.30319 The error is: Could not load file or assembly 'tests2' or one of its dependencies. The system cannot find the file specified. I've had a look in fuslogvw and it shows tests2 being searched for in the tests1\bin\debug and nunit-console folders. It never searches tests2\bin\debug even though it's specified on the command line. What's up with that?

  • How do i transfer this unmanaged code from asp to asp.net 2/mvc?

    - by melaos
    hi guys, i'm a newbie to ASP.net interop features, so what i have right here is some unmanaged dll that i need to call from my asp.net mvc app. the dll name is CTSerialNumChecksum.dll set CheckSumObj = Server.CreateObject("CTSerialNumChecksum.CRC32API") validSno = CheckSumObj.ValidateSerialNumber(no) i know it's unmanaged because when i try to add reference to the dll it doesn't work. i try to follow some tutorials on interop and marshalling but thus far i wasn't able to get the code to work. i'm trying to wrap the object into another static class and just let the rest of the app to call the code. using System; using System.Runtime.InteropServices; namespace OnlineRegisteration.Models { public static class SerialNumberChecksum { [DllImport("CTSerialNumChecksum")] public static extern int ValidateSerialNumber(string serialNo); } } Questions: How do i write the class? And what tool can i use to identify what type of dll a particular file is, i.e. unmanaged c++, etc? Also i intend to make use jquery to do ajax call later so i can use this to validate my form pre-submission. Is there a better way to handle this?

  • Upgrading VSTO project to .net 4 - What references do I actually need?

    - by Dana
    I'm developing an application for Office. It originally targeted .net 3.5, but I decided to upgrade to .net 4 because of some WPF issues that I've run into. When I switched all the projects in my solution and rebuilt, I got an error saying to include System.Xaml. I did that and rebuilt, and VS2010 told me to include another reference, so I did. This happened a couple more times, and finally it asked me to include Microsoft.Office.Tools.Common.v9.0, and when I did I got this error: Microsoft.Office.Tools.CustomTaskPaneCollection exists in both Microsoft.Office.Tools.Common.v9.0.dll and Microsoft.Office.Tools.Common.dll I have both Microsoft.Office.Tools.Common.v9.0 and Microsoft.Office.Tools.Common referenced in my project, but the problem is that if I remove either, I get an error. Am I doing something wrong? Is it odd that I would need both references? I find it strange that CustomTaskPaneCollection would be defined in two different binaries. If I remove Microsoft.Office.Tools.Common, the error that I get is "Cannot find the interop type that matches the embedded interop type 'Microsoft.Office.Tools.IAddInExtension'. Are you missing an assembly reference?"
